In the just-released first trailer for the movie (due in theaters in April 5), we learn that Bullock plays an FBI agent who finds herself sent to Boston to work on a case with a local crass-talking street detective, played by McCarthy.

The good times sure do roll. The two are shown dodging and firing bullets, conducting crazyass shakedowns (oops, did they really drop that guy from a fire escape?) and engaging in some off-duty drunk dancing.

"They're badass," Feig told me at the GQ Men of the Year party in L.A. "It's a very physical movie and they both bring their violence about in different ways."
